摘要
The invention relates to a method of preventing calcareous deposits on heated, water-cooled tools, for example welding or moulding tools for use in the drug or food industry, where the cooling water is used to ensure a particular temperature and an even distribution of temperature, the temperature of the tool being app. 90-120 DEG C, whereas the temperature of the cooling water in continuous operation never exceeds 30 DEG C. According to the invention the calcareous deposits are avoided by using recirculated cooling water, which is continuously regenerated and cooled. The invention also comprises a cooling unit for use in the implementation of the method, which unit has means (6, 12, 13, 19, 20) for recirculation and continuous regeneration of cooling water and has means (3, 4, 5, 8, 16, 18) for cooling of the cooling water. These means comprise calcium decomposition elements (7, 11) for separation of the calcium and elements (10) for ultraviolet irradiation of the cooling water for sterilization hereof.
